Novo and a couple of other companies are developing "ultra-rapid" human analogs. Novo is the closest to release and is hoped for then end of this year. I'm looking forward to this a great deal, but I do have some concerns about some of the techniques they're using to do this, and whether they have long-term implications for damage to insulin absorption sites. But then, I'll have to trust the experts, after all, I'm just an inquisitive electronics engineer.
